Any online shops that do port and polishing of stock manifolds to get a little more flow going?

Pic 253-20 top is 225Q, bottom is 180Q.
Pic 253-55 is fwd DP and cat from turbo (turbo partially shown at top left).
253-60 is 225Q DP at middle with 180Q/225Q cat assembly at top, 180Q DP at bottom (see similarity to fwd turbo and turbo DP before it splits).
You're concerned with the connection between the turbo and the midpipe (see 253-55 and compare to the 42DD DP - that's pretty much the assembly that the FWD has. You're replacing parts 2 & 3 on the 225Q with the 42DD, and would do parts 1 & 3 on the 180Q if a 42DD were available.
253-80 is FWD resonator/midpipe at bottom, with muffler and tailpipe at top. This pic and the last (253-85) are included as reference.
253-85 shows quattro resonator/midpipe at bottom, 180Q muffler and exhaust at middle, and 225Q muffler and exhaust at top.
